Galvanizing Steel Doors and Windows Process:
Shepherd Steel Doors and Windows can be Galvanized. This process has solved the issue of our high-quality steel doors and windows from rusting. They DO NOT RUST.
Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc. This reaction is a diffusion process, so the coating forms perpendicular to all surfaces creating a uniform thickness throughout the part.
The hot-dip galvanizing process has been used since 1742, providing long-lasting, maintenance-free corrosion protection at a reasonable cost for decades. Although hot-dip galvanizing has been utilized to protect steel for generations, the galvanizing process continues to evolve with new technologies and creative chemistries. The three main steps in the hot-dip galvanizing process are surface preparation, galvanizing, and post-treatment, each of which will be discussed in detail. The process is inherently simple, which is a distinct advantage over other corrosion protection methods.
